Similarly OT, a pet peeve of mine is how Germans and others consistently pronounce (the eg. SQL datatype) VARCHAR as var-CHAIR or sometimes var-CZAR (war czar, warczaw) when they pronounce CHAR/CHR correctly.

Disclaimer: not an English native speaker
I've always heard it pronounced var char (the parts rhyme). Char is pronounced like when you burn/blacken a steak. "Char-grilled food is cooked over or under direct heat so that its surface becomes slightly black"
If I were consciously trying to pronounce "char" as an English speaker would, I would probably say /tʃɑr/.
